A Coordinate System for Dynamical Instabilities in Hierarchical Systems in REBOUND
Tiger Lu, Garett Brown
We implement coordinates suitable for studying wide binary systems in TRACE, a hybrid integrator in the widely used open-source N-body integration package REBOUND. This is a regime…
On the statistical convergence of N-body simulations of the Solar System
Hanno Rein, Garett Brown, Mei Kanda
Most direct N-body integrations of planetary systems use a symplectic integrator with a fixed timestep. A large timestep is desirable in order to speed up the numerical simulations…
A substellar flyby that shaped the orbits of the giant planets
Garett Brown, Renu Malhotra, Hanno Rein
The modestly eccentric and non-coplanar orbits of the giant planets pose a challenge to solar system formation theories which generally indicate that the giant planets emerged from…
General relativistic precession and the long-term stability of the solar system
Garett Brown, Hanno Rein
The long-term evolution of the solar system is chaotic. In some cases, chaotic diffusion caused by an overlap of secular resonances can increase the eccentricity of planets when th…
On the long-term stability of the Solar System in the presence of weak perturbations from stellar flybys
Garett Brown, Hanno Rein
The architecture and evolution of planetary systems are shaped in part by stellar flybys. Within this context, we look at stellar encounters which are too weak to immediately desta…
A repository of vanilla long term integrations of the Solar System
Garett Brown, Hanno Rein
We share the source code and a 121 GB dataset of 96 long-term N-body simulations of the Solar System. This dataset can be analyzed by itself to study the dynamics of the Solar Syst…
On the accuracy of symplectic integrators for secularly evolving planetary systems
Hanno Rein, Garett Brown, Daniel Tamayo
Symplectic integrators have made it possible to study the long-term evolution of planetary systems with direct N-body simulations. In this paper we reassess the accuracy of such si…
High order symplectic integrators for planetary dynamics and their implementation in REBOUND
Hanno Rein, Daniel Tamayo, Garett Brown
Direct N-body simulations and symplectic integrators are effective tools to study the long-term evolution of planetary systems. The Wisdom-Holman (WH) integrator in particular has…
Hybrid Symplectic Integrators for Planetary Dynamics
Hanno Rein, David M. Hernandez, Daniel Tamayo +6
Hybrid symplectic integrators such as MERCURY are widely used to simulate complex dynamical phenomena in planetary dynamics that could otherwise not be investigated. A hybrid integ…
